Census of Population and Housing, 2000 [United States]: Public Use Microdata Sample: 1-Percent Sample (ICPSR 13511)

Principal Investigator(s):United States Department of Commerce. Bureau of the Census

Summary:

These Public Use Microdata Sample (PUMS) files contain
records representing 1-percent samples of the occupied and vacant
housing units in the United States and the people in the occupied
units in 2000. Group quarters people also are included. The files
contain individual weights for each person and housing unit, which
when applied to the individual records, expand the sample to the
relevant total. Some of the items included on the housing record are:
acreage, agricultural sales, bedrooms, condominium fee, contract rent,
cost of utilitie... (more info)

housing unit), vehicles available, year householder moved into unit,
and year structure was built. Some of the items included on the person
record are: ability to speak English, age, ancestry, citizenship,
class of worker, disability status, earnings in 1999, educational
attainment, grandparents as caregivers, Hispanic origin, hours worked,

status in 1999, and year of entry. The Public Use Microdata Sample
(PUMS) files contain geographic units known as super-Public Use
Microdata Areas (super-PUMAs) and Public Use Microdata Areas
(PUMAs). To maintain the confidentiality of the PUMS data, minimum
population thresholds are set for PUMAs and super-PUMAs. For the
1-percent state-level files, the super-PUMAs contain a minimum
population of 400,000 and are composed of a PUMA or a group of
contiguous PUMAs delineated on the 5-percent state-level PUMS
files. Super-PUMAs are a new geographic entity for Census 2000.
Super-PUMAs and PUMAs also are defined for place of residence on
April 1, 1995, and place of work.

(1) There are two files per part. The data file and
the PUMS Equivalency file. The data file is hierarchical. The housing
record has a record length of 316 with 106 variables and the person
record has a record length of 266 with 155 variables. The Equivalency
files list the geographic components (counties or MCDs, places, tracts
where available) and their assigned PUMA and super-PUMA codes. (2) The
codebook is provided by the principal investigator as a Portable
Document Format (PDF) file. The PDF file format was developed by Adobe
Systems Incorporated and can be accessed using PDF reader software,
such as the Adobe Acrobat Reader. Information on how to obtain a copy

A stratified sample of the population created by
subsampling the full census sample (approximately 15.8 percent of all
housing units) that received the 2000 Census "long-form"
questionnaire.
